My limited understanding of Texmacs is that Ghostscript is used to render PS/PDF objects and to create PS/PDF exports. It appears that success depends on the version of Ghostscript that is installed. It might also depend on the method used by Geobra to create the original PDF. I seem to recall that when I tried importing a PDF document that I had created, it rendered correctly in Ubuntu even though DS3.tm did not.
You could start with a live CD that already has the necessary software installed, e.g. Quantian 0.7.9.2 or liveTeXmacs 1.0.6, then you won't need to install anything! My impression is that Debian or Ubuntu installed to the (virtual) hard disc runs more quickly than a live CD on the same virtual machine. However, the live CD method lets you try the idea of a virtual computer more quickly and easily. See my previous e-mail for related comments on this.
[former mail:] The second step is to create a virtual machine. VirtualBox has a wizard which makes this easy. If you want to run Linux from a live CD, such as liveTexmacs or Quantian, then the virtual computer doesn't need a hard disc and can run entirely from the live CD (or an ISO image file attached to the virtual computer's CD-ROM drive). It won't use any space on your hard disc.
Instead of using a live CD, you can add a virtual hard disc to the virtual computer and install the Linux system of your choice. A 4GB virtual hard disc may be sufficient for most purposes. This arrangement has the advantage that you are not restricted by the selection of software on a live CD and can install whatever software you like.
The virtual hard disc is simply a file on your real hard disc. The virtual machine can easily be moved to another host computer by copying this file plus one very small file holding configuration data. This will, of course, include any files that you saved to the virtual hard disc. You could even keep the virtual hard disc's file on a USB drive and carry it with you. If the drive is large enough, it could also hold a copy of VirtualBox, so that you have everything you need to install both VirtualBox and the virtual machine onto any computer.
I am also still experimenting with installing Debian Linux onto a bootable USB drive. I had a few problems but am making progress. Personally, though, I think I prefer the virtual machine approach.
YES !!I'd be happy to write a recipe showing how to install and set it up (it isn't difficult actually).
Note that Quantian is a very big download at 2.7GB but has lots of software already installed! Live Texmacs is smaller (700MB approx) but the server is slow and I found it quicker to download Quantian.
Hope this helps.
Paul.

NOTES
- Texmacs can import a page or graphic in PDF format and embed it into the document like any other graphic. This can be useful for importing graphics produced by other software. It doesn't work on all platforms but it works well on Debian 4.0 (I suspect it depends which version of Ghostscript is installed).
- Doesn't work with DS3.tm. The document is correct in Texmacs but, when exported to PS/PDF, the graphics appear full-page (or not at all) and overlay one another.
- Doesn't work with DS3.tm. When DS3.tm is opened in Texmacs the rendering of the imported PDF is very unreliable. When the document is exported to PS/PDF, the graphics appear full-page (or not at all) and overlay one another.
- The version supplied (or available from the official package repository) is not compatible with the supplied version of Texmacs.
- Can be made to work with some minor setting up.
- Not included (possibly could be added).
- GNUplot crashes immediately with error message "error while loading shared libraries: libwx_gtk2ud_richtext-2.8.so.0: cannot open shared object: No such file or directory"
